AD: Pratt & Whitney Division Turbofan Engines

AD NUMBER: 2019-06-07

PRODUCT: Certain Pratt & Whitney Division (PW) PW4164, PW4164-1D, PW4168, PW4168-1D, PW4168A, PW4168A-1D, and PW4170 model turbofan engines.

ACTION: Final Rule.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2016-22-05 for the engines listed above.

AD 2016-22-05 required initial and repetitive inspections of the affected fuel nozzles and their replacement with parts eligible for installation.

This AD requires initial and repetitive inspections of the affected fuel nozzles and fuel nozzle supply manifold assemblies, replacement of the affected fuel nozzles with parts eligible for installation, and the installation of new brackets and clamps on the fuel nozzle supply manifold assemblies.

This AD was prompted by several instances of fuel leaks on PW engines with the Talon IIB combustion chamber configuration installed.

DATES: This AD is effective May 2, 2019.

COST: The FAA estimates that this AD affects 72 engines installed on airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

  • Inspect fuel nozzles: 2.2 work-hours × $85 per hour = $187 per engine.
  • Open and close cowl doors: (on-wing) 1 work-hour × $85 per hour = $85 per engine
  • Remove and replace (24) fuel nozzles: 48 work-hours × $85 per hour = $4,080, Parts $423,471. Cost per engine: $427,551
  • Remove and re-install necessary hardware according to AMM: 23 work-hours × $85 per hour = $1,955 per engine
  • Replace Fuel Nozzle Supply Manifold Assemblies and install new clamps/brackets: 16 work-hours × $85 per hour = $1,360. Parts $77,159. Cost per engine: $78,519
